01 - In a mixing bowl, beat the cream cheese, granulated sugar, egg yolk, vanilla extract, and lemon zest together until smooth and creamy with no lumps remaining.
02 - Lay an egg roll wrapper flat with one corner pointing toward you. Spoon 1 to 2 tablespoons of cheesecake filling near the corner closest to you.
03 - Fold the bottom corner up and over the filling, then fold in both sides tightly. Continue rolling away from you and seal the top edge with a flour-and-water paste.
04 - Continue filling, rolling, and sealing the remaining wrappers until all 12 egg rolls are assembled.
05 - Pour vegetable oil into a deep fryer or heavy skillet and heat to 350°F.
06 - Carefully lower egg rolls into the hot oil in small batches. Fry for 2 to 3 minutes, turning occasionally, until evenly golden brown on all sides.
07 - Using a slotted spoon, transfer the fried egg rolls to a paper-towel-lined plate to drain.
08 - Dust generously with powdered sugar and serve warm alongside fresh berries or drizzled with chocolate or caramel sauce.
